Description

This plugin plots the position of various pulsars, with object information about each one. Pulsar data is derived from Catalog of Pulsars (Taylor+ 1995) for 0.1.x series and derived from The ATNF Pulsar Catalogue (Manchester, R. N., Hobbs, G. B., Teoh, A. & Hobbs, M., Astron. J., 129, 1993-2006 (2005) (astro-ph/0412641)) for series 0.2.x.

Using the Pulsars plugin

Enable the tool by clicking the tool-bar button "Load at startup"

Find the pulsar by their designation (PSR J0437-4715 as example)

Catalog of pulsars

You can modify the catalog.json (for 0.1.x) or pulsars.json (for 0.2.x) file manually using a text editor. If you are using Windows, it is strongly recommended to use an advanced text editor such as Notepad++ to avoid problems with end-of-line characters. (It will also color the JSON code and make it easier to read.)

Warning: Before editing your JSON file, make a backup copy. Leaving out the smallest detail (such as a comma or forgetting to close a curly bracket) will prevent Stellarium from starting.

The path to the directory which contains catalog.json or pulsars.json is something like:
